Insights

Equity research analyst

Results show strong top-line growth and commercial expansion, with leverage and backlog worth watching.

BWX Technologies delivered revenue of $860.2 million, up 26.1% year over year, as Commercial Operations more than doubled to $283.6 million. Government Operations grew modestly to $577.9 million, keeping the portfolio anchored in U.S. defense and nuclear work.

Operating income increased to $106.7 million, with Commercial segment operating income rising to $24.0 million and margins improving to 8.5%. The effective tax rate fell to 15.0%, helped by equity compensation tax benefits, supporting net income of $91.2 million and diluted EPS of $0.99.

Backlog reached $8.65 billion, and management expects about 60% of this to convert to revenue by 2027. Liquidity includes $520.3 million of cash and restricted cash plus an undrawn $1.25 billion revolver, offset by $2.02 billion of long‑term debt and $1.25 billion of 0% convertible notes due 2030. The planned acquisition of Precision Components Group adds future growth exposure to U.S. commercial nuclear demand, subject to regulatory approvals and integration execution.

6 terms

remaining performance obligations financial

"At March 31, 2026, our remaining performance obligations were $8,650.8 million."

Remaining performance obligations are the work a company still needs to complete for its customers, like finishing a service or delivering a product. It’s important because it shows how much future income the company has coming in from current agreements, giving a clearer picture of its ongoing business.

cost-to-cost method financial

"We generally recognize contract revenues and related costs over time ... based on a cost-to-cost method."

Convertible Senior Notes financial

"the Company issued $1.25 billion aggregate principal amount of 0% Convertible Senior Notes due 2030"

Convertible senior notes are a type of loan that a company issues to investors, which can be turned into company shares later on. They are called "senior" because they are paid back before other debts if the company runs into trouble. This allows investors to earn interest like a loan but also have the chance to own part of the company if its value rises.

capped call transactions financial

"the Company paid $131.9 million to enter into privately negotiated capped call transactions"

Capped call transactions are agreements where investors buy options that give them the chance to benefit if a stock's price goes up, but with a limit on how much they can gain. This helps protect them from paying too much if the stock's price rises a lot, similar to having a maximum limit on a reward. They matter because they help investors manage risk while still allowing some upside potential.

cash flow hedges financial

"We have designated the majority of our FX forward contracts that qualify for hedge accounting as cash flow hedges."

A cash flow hedge is an accounting label companies use when they enter financial contracts—like currency or interest-rate agreements—to protect expected future cash payments or receipts from unpredictable moves. For investors, it signals that the company is trying to smooth out future cash variability (think of locking in a price to avoid surprises), which can reduce reported profit swings but also means the company has exposure to derivative instruments and their associated risks.

effective tax rate financial

"Our effective tax rate for the three months ended March 31, 2026 was 15.0%"

The effective tax rate is the percentage of a company's profits that it pays in taxes. It shows how much of its earnings go to taxes after all deductions and credits are considered. For investors, it indicates how much of the company's income is taken by taxes, impacting overall profitability and financial health.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

MARCH 31, 2026

(UNAUDITED)

NOTE 1 – BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

We have presented the condensed consolidated financial statements of BWX Technologies, Inc. ("BWXT" or the "Company") in U.S. dollars in accordance with the interim reporting requirements of Form 10-Q, Rule 10-01 of Regulation S-X and accounting principles generally accepted in the United States ("GAAP"). Certain financial information and disclosures normally included in our financial statements prepared annually in accordance with GAAP have been condensed or omitted. Readers of these financial statements should, therefore, refer to the consolidated financial statements and notes in our annual report on Form 10-K for the year ended December 31, 2025 (our "2025 10-K"). We have included all adjustments, in the opinion of management, consisting only of normal recurring adjustments, necessary for a fair presentation.

We use the equity method to account for investments in entities that we do not control, but over which we have the ability to exercise significant influence. We generally refer to these entities as "joint ventures". We have eliminated all intercompany transactions and accounts. We classify assets and liabilities related to long-term contracts as current using the duration of the related contract or program as our operating cycle, which is generally longer than one year. We present the notes to our condensed consolidated financial statements on the basis of continuing operations, unless otherwise stated.

Unless the context otherwise indicates, "we," "us" and "our" mean BWXT and its consolidated subsidiaries.

Reportable Segments

We operate in two reportable segments: Government Operations and Commercial Operations. Our reportable segments are further described as follows:

•Our Government Operations segment manufactures naval nuclear reactors, including the related nuclear fuel, for the U.S. Naval Nuclear Propulsion Program for use in submarines and aircraft carriers. Through this segment, we also fabricate fuel-bearing precision components that range in weight from a few grams to hundreds of tons, manufacture electro-mechanical equipment, perform design, manufacturing, inspection, assembly and testing activities and downblend Cold War-era government stockpiles of high-enriched uranium, develop capabilities related to the manufacture of high-purity depleted uranium, design advanced reactors and manufacture other advanced materials and products for commercial, military and space applications. In addition, we supply proprietary and sole-source valves, manifolds and fittings to global naval and commercial shipping customers. In-house capabilities also include wet chemistry uranium processing, advanced heat treatment to optimize component material properties and a controlled, clean-room environment with the capacity to assemble railcar-size components. This segment also provides various other services, primarily through joint ventures, to the U.S. and Canadian Governments including nuclear materials management and operation, environmental management and administrative and operating services for various Government-owned facilities. These services are provided to the U.S. Department of Energy ("DOE"), including the National Nuclear Security Administration, the Office of Nuclear Energy, the Office of Science and the Office of Environmental Management, the Department of War (also known as the Department of Defense), NASA and Canadian Nuclear Labs. In addition, this segment also develops technology for advanced nuclear reactors for a variety of power and propulsion applications in the space and terrestrial domains and offers complete advanced nuclear fuel and reactor design and engineering, licensing and manufacturing services for these programs.

•Our Commercial Operations segment fabricates commercial nuclear steam generators, nuclear fuel, fuel handling systems, pressure vessels, reactor components, heat exchangers, tooling delivery systems and other auxiliary equipment, including containers for the storage of spent nuclear fuel and other high-level waste and supplies nuclear-grade materials and precisely machined components for nuclear utility customers. We supply the global nuclear industry with large, heavy components and are the only commercial heavy nuclear component manufacturer in North America. This segment also provides specialized engineering services that include structural component design, 3-D thermal-hydraulic engineering analysis, weld and robotic process development, electrical and controls engineering and metallurgy and materials engineering. In addition, this segment offers in-plant inspection, maintenance and modification services for nuclear steam generators, heat exchangers, reactors, fuel handling systems and balance of plant equipment, as well as specialized non-destructive examination and tooling/repair solutions. This segment also offers a broad suite of nuclear power plant lifecycle support and management services for the global industry and transmission and distribution markets. This segment also manufactures medical radioisotopes, radiopharmaceuticals and medical devices, and partners with life science and pharmaceutical companies developing new drugs.

Table of Contents

See Note 3 and Note 8 for financial information about our segments. Operating results for the three months ended March 31, 2026 are not necessarily indicative of the results that may be expected for the year ending December 31, 2026. For further information, refer to the consolidated financial statements and notes included in our 2025 10-K.

Recently Adopted Accounting Standards

There were no accounting standards adopted during the three months ended March 31, 2026 that had a significant impact on our financial position, results of operations, cash flows or disclosures.

Contracts and Revenue Recognition

We generally recognize contract revenues and related costs over time for individual performance obligations based on a cost-to-cost method in accordance with Financial Accounting Standards Board ("FASB") Topic Revenue from Contracts with Customers. We recognize estimated contract revenue and resulting income based on the measurement of the extent of progress toward completion as a percentage of the total project. Certain costs may be excluded from the cost-to-cost method of measuring progress, such as significant costs for uninstalled materials, if such costs do not depict our performance in transferring control of goods or services to the customer. We review contract price and cost estimates periodically as the work progresses and reflect adjustments proportionate to the percentage-of-completion in income in the period when those estimates are revised. We recognize revenue on certain cost plus and time and materials contracts equal to the amount we have the right to invoice the customer when performance obligations are satisfied over time and the invoice amount corresponds directly with the value we are providing the customer. Certain of our contracts recognize revenue at a point in time, and revenue on these contracts is recognized when control transfers to the customer. The majority of our revenue that is recognized at a point in time is related to parts and certain medical radioisotopes and radiopharmaceuticals in our Commercial Operations segment. For all contracts, if a current estimate of total contract cost indicates a loss on a contract, the projected loss is recognized in full when determined.

See Note 3 for a further discussion of revenue recognition.

Provision for Income Taxes

We are subject to federal income tax in the U.S., Canada and various other foreign jurisdictions, as well as income tax within multiple U.S. state jurisdictions. We provide for income taxes based on the enacted tax laws and rates in the jurisdictions in which we conduct our operations. These jurisdictions may have regimes of taxation that vary with respect to nominal rates and with respect to the basis on which these rates are applied. This variation, along with changes in our mix of income within these jurisdictions, can contribute to shifts in our effective tax rate from period to period.

Our effective tax rate for the three months ended March 31, 2026 was 15.0% as compared to 17.7% for the three months ended March 31, 2025. The effective tax rates for the three months ended March 31, 2026 and March 31, 2025 were lower than the U.S. corporate federal income tax rate of 21% primarily due to excess tax benefits associated with equity compensation.

Cash and Cash Equivalents and Restricted Cash and Cash Equivalents

At March 31, 2026, we had restricted cash and cash equivalents totaling $8.0 million, $4.8 million of which was held for future decommissioning of facilities (which is included in Other Assets on our condensed consolidated balance sheets) and $3.2 million of which was held to meet reinsurance reserve requirements of our captive insurer.

The following table provides a reconciliation of cash and cash equivalents and restricted cash and cash equivalents on our condensed consolidated balance sheets to the totals presented on our condensed consolidated statements of cash flows:

						March 31, 2026						December 31, 2025
						(In thousands)

Derivative Financial Instruments

Our operations give rise to exposure to market risks from changes in foreign currency exchange ("FX") rates. We use derivative financial instruments, primarily FX forward contracts, to reduce the impact of changes in FX rates on our operating results. We use these instruments to hedge our exposure associated with revenues or costs on our long-term contracts and other transactions that are denominated in currencies other than our operating entities' functional currencies. We do not hold or issue derivative financial instruments for trading or other speculative purposes.

We enter into derivative financial instruments primarily as hedges of certain firm purchase and sale commitments and loans between domestic and foreign subsidiaries denominated in foreign currencies. We record these contracts at fair value on our condensed consolidated balance sheets. Based on the hedge designation at the inception of the contract, the related gains and losses on these contracts are deferred in stockholders' equity as a component of Accumulated other comprehensive income (loss) until the hedged item is recognized in earnings. The gain or loss on a derivative instrument not designated as a hedging instrument is immediately recognized in earnings. Gains and losses on derivative financial instruments that require immediate recognition are included as a component of Other – net on our condensed consolidated statements of income and are recorded in our condensed consolidated statements of cash flows based on the nature and use of the instruments.

We have designated the majority of our FX forward contracts that qualify for hedge accounting as cash flow hedges. The hedged risk is the risk of changes in functional-currency-equivalent cash flows attributable to changes in FX spot rates of forecasted transactions primarily related to long-term contracts. We exclude from our assessment of effectiveness the portion of the fair value of the FX forward contracts attributable to the difference between FX spot rates and FX forward rates. At March 31, 2026, we had deferred approximately $0.2 million of net gains on these derivative financial instruments. Assuming market conditions continue, we expect to recognize the majority of this amount in the next 12 months. For the three months ended March 31, 2026 and 2025, we recognized losses (gains) of $4.0 million and $(1.7) million, respectively, in Other – net on our condensed consolidated statements of income associated with FX forward contracts not designated as hedging instruments.

At March 31, 2026, our derivative financial instruments consisted of FX forward contracts with a total notional value of $252.7 million with maturities extending to December 2028. These instruments consist primarily of FX forward contracts to purchase or sell Canadian dollars and Euros. We are exposed to credit-related losses in the event of non-performance by counterparties to derivative financial instruments. We attempt to mitigate this risk by using major financial institutions with high credit ratings. Our counterparties to derivative financial instruments have the benefit of the same collateral arrangements and covenants as described under our credit facility.

New Accounting and Disclosure Standards

In November 2024, the FASB issued updates to Topic Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures: Disaggregation of Income Statement Expenses. These updates require a public entity to disclose additional information about specific expense categories in the notes to financial statements on an annual and interim basis. The updates are effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. A public entity may apply these amendments on a prospective basis or retrospectively to any or all prior periods presented in the financial statements. We are currently evaluating the impact of the adoption of this standard and expect that it will only require changes to our disclosures with no impact on our results of operations, financial position or cash flows and disclosures.

In September 2025, the FASB issued updates to Topic Intangibles – Goodwill and Other – Internal-Use Software: Targeted Improvements to the Accounting for Internal-Use Software. These updates modernize the accounting for internal-use software by eliminating the sequential development stages currently in use, and modify when an entity is required to begin capitalizing software costs. Furthermore, disclosures for property, plant and equipment will be required for all capitalized software costs. The updates are effective for annual reporting periods beginning after December 15, 2027 and interim reporting periods within those annual reporting periods. Early adoption is permitted. Upon adoption, the updates may be applied prospectively, retrospectively or using a modified transition approach. We are currently evaluating the impact of the adoption of this standard on our financial condition, results of operations, cash flows and disclosures.

In December 2025 the FASB issued updates to Topic Government Grants – Accounting for Government Grants Received

by Business Entities. These updates add guidance on the recognition, measurement and presentation of government grants

where entities historically were required to analogize other existing guidance to determine the appropriate accounting. The

FASB largely leveraged this other guidance in these updates. The updates are effective for annual periods beginning after

December 15, 2028, including interim periods within those fiscal years with early adoption permitted. We are currently

evaluating the impact of the adoption of this standard.

NOTE 3 – REVENUE RECOGNITION

As described in Note 1, our operations are assessed based on two reportable segments.

Performance Obligations

As we progress on our contracts and the underlying performance obligations for which we recognize revenue over time, we refine our estimates of variable consideration and total estimated costs at completion, which impact the overall profitability on our contracts and performance obligations. Changes in these estimates result in the recognition of cumulative catch-up adjustments that impact our revenues and/or costs of contracts. The aggregate impact of changes in estimates decreased our revenues and operating income as follows:

						Three Months Ended March 31,
						2026						2025
						(In thousands)
Revenues (1)						$	(5,302)					$	(11,590)
Operating Income (1)						$	(5,727)					$	(11,558)

(1)During the three months ended March 31, 2026 and 2025, no adjustments to any one contract had a material impact on our consolidated financial statements.

Contract Assets and Liabilities

We include revenues and related costs incurred, plus accumulated contract costs that exceed amounts invoiced to customers under the terms of the contracts, in Contracts in progress. Costs specific to certain contracts for which we recognize revenue at a point in time are also included in Contracts in progress. We include in Advance billings on contract billings that exceed accumulated contract costs and revenues recognized over time. Amounts that are withheld on our fixed-price incentive fee contracts are classified within Retainages. Certain of these amounts require conditions other than the passage of time to be achieved, with the remaining amounts only requiring the passage of time. Most long-term contracts contain provisions for progress payments. Our unbilled receivables do not contain an allowance for credit losses as we expect to invoice customers and collect all amounts for unbilled receivables. Changes in Contracts in progress and Advance billings on contracts are primarily driven by differences in the timing of revenue recognition and billings to our customers. Our fixed-price incentive fee contracts for our Government Operations segment include provisions that result in an increase in retainages on contracts during the first and third quarters of the year, with larger payments received during the second and fourth quarters. Retainages also vary as a result of timing differences between incurring costs and achieving milestones that allow us to recover these amounts.

						March 31,						December 31,
						2026						2025
						(In thousands)
Included in Contracts in progress:
Unbilled receivables						$	645,735					$	594,749
Retainages						$	77,542					$	46,311
Advance billings on contracts						$	271,587					$	305,285

During the three months ended March 31, 2026 and 2025, we recognized $67.3 million and $69.5 million, respectively, of revenues that were in Advance billings on contracts at the beginning of each year.

Remaining Performance Obligations

Remaining performance obligations represent the dollar amount of revenue we expect to recognize in the future from performance obligations on contracts previously awarded and in progress. At March 31, 2026, our remaining performance obligations were $8,650.8 million. We expect to recognize approximately 60% of the revenue associated with our remaining performance obligations by the end of 2027, with the remainder to be recognized thereafter.

NOTE 4 – PENSION PLANS AND POSTRETIREMENT BENEFITS

We record the service cost component of net periodic benefit cost within Operating income on our condensed consolidated statements of income. For the three months ended March 31, 2026 and 2025, these amounts were $5.3 million and $1.8 million, respectively. All other components of net periodic benefit cost are included in Other – net within the condensed consolidated statements of income. For the three months ended March 31, 2026 and 2025, these amounts were $(4.0) million and $(1.7) million, respectively.

NOTE 6 – FAIR VALUE MEASUREMENTS

Investments

The following is a summary of our investments measured at fair value at March 31, 2026:

						Total						Level 1						Level 2						Level 3						Unclassified
						(In thousands)
Equity securities
Mutual funds						$	7,947					$	—					$	7,947					$	—					$	—
Total						$	7,947					$	—					$	7,947					$	—					$	—

The following is a summary of our investments measured at fair value at December 31, 2025:

						Total						Level 1						Level 2						Level 3						Unclassified
						(In thousands)
Equity securities
Mutual funds						$	8,243					$	—					$	8,243					$	—					$	—
Total						$	8,243					$	—					$	8,243					$	—					$	—

We estimate the fair value of investments based on quoted market prices. For investments for which there are no quoted market prices, we derive fair values from available yield curves for investments of similar quality and terms.

Derivatives

Level 2 derivative assets and liabilities currently consist of FX forward contracts. Where applicable, the value of these derivative assets and liabilities is computed by discounting the projected future cash flow amounts to present value using

15

Table of Contents

market-based observable inputs, including FX forward and spot rates, interest rates and counterparty performance risk adjustments. At March 31, 2026 and December 31, 2025, we had FX forward contracts outstanding to purchase or sell foreign currencies, primarily Canadian dollars and Euros, with a total fair value of $1.2 million and $5.2 million, respectively. Derivative assets and liabilities are included in Accounts receivable – other and Accounts payable, respectively, on our condensed consolidated balance sheets.

Other Financial Instruments

We used the following methods and assumptions in estimating our fair value disclosures for our other financial instruments, as follows:

Cash and cash equivalents and restricted cash and cash equivalents. The carrying amounts that we have reported in the accompanying condensed consolidated balance sheets for Cash and cash equivalents and Restricted cash and cash equivalents approximate their fair values due to their highly liquid nature.

Long-term and short-term debt. We base the fair values of debt instruments, including our Senior Notes, on quoted market prices. Where quoted prices are not available, we base the fair values on the present value of future cash flows discounted at estimated borrowing rates for similar debt instruments or on estimated prices based on current yields for debt issues of similar quality and terms. At March 31, 2026, the fair value of the Senior Notes due 2028, Senior Notes due 2029, and 2030 Notes was $384.5 million, $388.3 million, and $1.285 billion, respectively. At December 31, 2025, their fair values were $392.9 million, $389.3 million, and $1.194 billion, respectively. The fair value of our remaining debt instruments approximated their carrying values at March 31, 2026 and December 31, 2025.

Note receivable. Included in Other current assets is a note receivable related to a third-party loan. We base the fair value of this level 2 note receivable instrument on the present value of future cash flows discounted at market interest rates for financial instruments with similar quality and terms. At March 31, 2026 and December 31, 2025, the carrying value of our note receivable was $6.2 million and $6.4 million, respectively, and approximated its fair value.

NOTE 7 – STOCK-BASED COMPENSATION

Stock-based compensation recognized for all of our plans for the three months ended March 31, 2026 and 2025 totaled $10.2 million and $5.0 million, respectively, with associated tax benefit totaling $2.3 million and $1.0 million, respectively.

Information about our Major Customers:

In the three months ended March 31, 2026 and 2025, sales to the U.S. Government accounted for approximately 89% and 92% of our Government Operations segment revenues, respectively. In the three months ended March 31, 2026 and 2025, sales to two large utility customers accounted for approximately 61% and 73% of our Commercial Operations segment revenues, respectively.

Evaluation of segment performance:

Our Chief Operating Decision Maker ("CODM") measures the performance of each segment based on several metrics, including revenue and operating income and uses these results, in part, to evaluate the performance of and to allocate resources to each segment. Our CODM does not use assets by segment to evaluate segment performance or allocate resources. Consequently, we do not disclose assets by segment.

Item 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following information should be read in conjunction with the unaudited condensed consolidated financial statements and the notes thereto included in Item 1 in Part I of this quarterly report on Form 10-Q ("Report"), as well as the audited consolidated financial statements and the related notes and Item 7 of our annual report on Form 10-K for the year ended December 31, 2025 (our "2025 10-K").

In this Report, unless the context otherwise indicates, "we," "us" and "our" mean BWX Technologies, Inc. ("BWXT" or the "Company") and its consolidated subsidiaries.

Cautionary Statement Concerning Forward-Looking Statements

From time to time, our management or persons acting on our behalf make forward-looking statements to inform existing and potential security holders about our Company. Forward-looking statements include those statements that express a belief, expectation or intention, as well as those that are not statements of historical fact, within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Statements and assumptions regarding expectations and projections of specific projects, our future backlog, revenues, income, capital spending, strategic investments, acquisitions or divestitures, return of capital activities or margin improvement initiatives are examples of forward-looking statements. Forward-looking statements are generally accompanied by words such as "estimate," "project," "predict," "believe," "expect," "anticipate," "plan," "seek," "goal," "could," "intend," "may," "should" or other words that convey the uncertainty of future events or outcomes. In addition, sometimes we will specifically describe a statement as being a forward-looking statement and refer to this cautionary statement.

We have based our forward-looking statements on information currently available to us and our current expectations, estimates and projections about our Company, industries and business environment. We caution that these statements are not guarantees of future performance and you should not rely unduly on them as they involve risks, uncertainties and assumptions that we cannot predict. In addition, we have based many of these forward-looking statements on assumptions about future events that may prove to be inaccurate. While our management considers these statements and assumptions to be reasonable, they are inherently subject to numerous factors, including potentially the risk factors described in Item 1A of our 2025 10-K, most of which are difficult to predict and many of which are beyond our control. As a contractor to the U.S. Government, such risks include, without limitation, budget uncertainty, the risk of future budget cuts, the impact of continuing resolution funding mechanisms and the debt ceiling, the risk of government shutdowns, including the risk of program cancellations, schedule delays, production halts and other disruptions and nonpayment, and changing funding and acquisition priorities. Accordingly, our actual results may differ materially from the future performance that we have expressed or forecast in our forward-looking statements.

We have discussed many of these factors in more detail elsewhere in this Report. These factors are not necessarily all the factors that could affect us. Unpredictable or unanticipated factors we have not discussed in this Report or in our 2025 10-K could also have material adverse effects on actual results of matters that are the subject of our forward-looking statements. We do not intend to update or review any forward-looking statement or our description of important factors, whether as a result of new information, future events or otherwise, except as required by applicable laws.

General

We are a leading supplier of nuclear components and fuel to the U.S. Government; provide technical, management and site services to support governments in the operation of complex facilities and environmental remediation activities; supply precision manufactured components, nuclear fuel and services for the commercial nuclear power industry; supply critical medical radioisotopes and radiopharmaceuticals; and develop nuclear technologies for a variety of applications, including medical radioisotopes, advanced nuclear power sources and advanced nuclear reactors.

We operate in two reportable segments: Government Operations and Commercial Operations. In general, we operate in capital-intensive industries and rely on large contracts for a substantial amount of our revenues. We are currently exploring growth strategies across our segments through strategic investments and acquisitions to expand and complement our existing businesses. We would expect to fund these opportunities with cash generated from operations or by raising additional capital through debt, equity or some combination thereof.

Government Operations

The revenues of our Government Operations segment are largely a function of national security spending by the U.S. Government. As a supplier of major nuclear components for certain U.S. Government programs, we are a significant participant in the defense industry and have not been negatively impacted by federal budget reductions to date. We believe many of our programs are well-aligned with national defense and other strategic priorities. However, it is possible that reductions in federal government spending could have an adverse impact on the operating results and cash flows of this segment in the future.

Through this segment, we engineer, design and manufacture precision naval nuclear components, reactors and nuclear fuel for the U.S. Department of Energy ("DOE")/National Nuclear Safety Administration's ("NNSA") Naval Nuclear Propulsion Program. In addition, this segment downblends Cold War-era government stockpiles of high-enriched uranium, develops and manufactures advanced materials and products for commercial, military and space applications and supplies proprietary and sole-source valves, manifolds and fittings to global naval and commercial shipping customers. As a supplier of major nuclear components for certain U.S. Government programs, this segment is a significant participant in the defense industry.

This segment also provides various services to the U.S. Government by managing and operating high-consequence operations at U.S. nuclear weapons sites, national laboratories and manufacturing complexes. The revenues and equity income of investees under these types of contracts are largely a function of spending by the U.S. Government and the performance scores we and our consortium partners earn in managing and operating these sites. With our specialized capabilities of full life-cycle management of special materials, facilities and technologies, we believe this segment is well-positioned to continue participating in the ongoing cleanup, operation and management of critical government-owned nuclear sites, laboratories and manufacturing complexes maintained by the DOE and other federal agencies.

Additionally, this segment also develops technology for a variety of applications, including advanced nuclear power sources, and offers complete advanced nuclear fuel and reactor design and engineering and licensing and manufacturing services for new advanced nuclear reactors.

Commercial Operations

Through this segment, we design and manufacture commercial nuclear steam generators, heat exchangers, pressure vessels, reactor components, as well as other auxiliary equipment, including containers for the storage of spent nuclear fuel and other high-level nuclear waste. This segment is a leading supplier of nuclear fuel, fuel handling systems, tooling delivery systems, nuclear-grade materials and precisely machined components, and related services for nuclear power plants. This segment also provides a variety of engineering and in-plant services and offers a broad suite of lifecycle support and management services for the global nuclear power industry, transmission and distribution markets. This segment is a significant supplier to nuclear power utilities undergoing major refurbishment and plant life extension projects and is a global manufacturer and supplier of critical medical radioisotopes and radiopharmaceuticals.

Our Commercial Operations segment's overall activity primarily depends on the demand and competitiveness of nuclear energy and the demand for critical radioisotopes and radiopharmaceuticals. A significant portion of our Commercial Operations segment's operations depends on the timing of maintenance and refueling outages, the cyclical nature of capital expenditures and major refurbishment and plant life extension projects, as well as the demand for nuclear fuel and fuel handling equipment and engineering services primarily in the Canadian market, which could cause variability in our financial results.

Acquisitions

Aerojet Ordnance Tennessee, Inc.

On January 3, 2025, we completed the acquisition of Aerojet Ordnance Tennessee, Inc. ("A.O.T."), a subsidiary of L3Harris Technologies, Inc. A.O.T. is a leading provider of advanced special materials which will further enhance our capabilities to develop and manufacture advanced materials and products for commercial, military and space applications. A.O.T. is reported as part of our Government Operations segment.

Kinectrics Inc.

On May 20, 2025, we acquired all of the equity interests of Kinectrics Holdings Inc., the parent company of Kinectrics Inc. ("Kinectrics"). Kinectrics is a leader in providing lifecycle management services for the global nuclear power and transmission and distribution markets, and in the production and supply of isotopes for the radiopharmaceutical industry which

will enable us to expand our portfolio of products and services in the global nuclear market. Kinectrics is reported as part of our Commercial Operations segment.

Precision Components Group, LLC

Subsequent to March 31, 2026, we announced our intention to acquire Precision Components Group, LLC ("PCG"), including its subsidiaries Precision Custom Components and DC Fabricators. PCG is a privately held U.S. manufacturer of complex, heavy-walled and heat-transfer components. The acquisition will expand BWXT’s heavy-manufacturing footprint and establish additional U.S. commercial nuclear production capacity to serve growing domestic demand. The acquisition is expected to close during the second half of 2026, subject to required regulatory approvals and customary closing conditions. Once completed, PCG will be reported as part of our Commercial Operations segment.

See Note 2 to our condensed consolidated financial statements for additional information about our recent acquisition activity.

Critical Accounting Estimates

For a summary of the critical accounting policies and estimates that we use in the preparation of our unaudited condensed consolidated financial statements, see Item 7 of our 2025 10-K. There have been no material changes to our critical accounting policies and estimates during the three months ended March 31, 2026.

Contracts & Revenue Recognition

We generally recognize contract revenue and resulting income over time based on the measurement of the extent of progress toward completion using total costs incurred as a percentage of the total estimated project costs for individual performance obligations. We review contract price and cost estimates periodically as the work progresses and reflect adjustments proportionate to the percentage-of-completion in income in the period when those estimates are revised. If a current estimate of total contract costs indicates a loss on a contract, the projected loss is recognized in full when determined.

As we progress on our contracts and the underlying performance obligations, we refine our estimates of variable consideration and total estimated costs at completion, which impact the overall profitability on our contracts and performance obligations. Changes in these estimates result in the recognition of cumulative catch-up adjustments that impact our revenues and/or costs of contracts. The aggregate impact of changes in estimates decreased our revenues and operating income as follows:

Revenues (1)						$	(5,302)					$	(11,590)
Operating Income (1)						$	(5,727)					$	(11,558)

(1)During the three months ended March 31, 2026 and 2025, no adjustments to any one contract had a material impact on our consolidated financial statements.

Contracts may be modified at the request of our customer or initiated by us to amend all or part of an existing contract, including contract type. Depending on the nature of the modification, we consider whether to account for the modification as an adjustment to the existing contract or as a separate contract. Modifications to our contracts are generally accounted for as if they were part of the existing contract as these modifications are not distinct from the existing contract and accounted for as a cumulative adjustment to revenue.

Consolidated Results of Operations

Three months ended March 31, 2026 vs. 2025

Consolidated revenues increased 26.1%, or $178.0 million, to $860.2 million in the three months ended March 31, 2026 compared to $682.3 million for the corresponding period of 2025, due to increases in our Government Operations and Commercial Operations segments of $22.6 million and $155.3 million, respectively.

Consolidated operating income increased $10.1 million to $106.7 million in the three months ended March 31, 2026 compared to $96.6 million for the corresponding period of 2025 due to increases in our Government Operations and Commercial Operations segments of $1.4 million and $17.6 million, respectively, offset partially by higher Unallocated Corporate expenses of $8.9 million when compared to the corresponding period in the prior year.

Three months ended March 31, 2026 vs. 2025

Revenues increased $22.6 million, or 4.1%, to $577.9 million in the three months ended March 31, 2026 compared to $555.3 million for the corresponding period of 2025. The increase was primarily due to an increase in revenues of $16.2 million associated with A.O.T. and contributions from enrichment operations. These increases were partially offset by a decrease in revenues associated with our advanced technologies business.

Operating income increased $1.4 million to $99.1 million in the three months ended March 31, 2026 compared to $97.7 million for the corresponding period of 2025 primarily due to the operating income impact of the changes in revenue noted above.

Three months ended March 31, 2026 vs. 2025

Revenues increased 121.1%, or $155.3 million, to $283.6 million in the three months ended March 31, 2026 compared to $128.3 million for the corresponding period of 2025. The increase was primarily related to the acquisition of Kinectrics, completed on May 20, 2025, which resulted in an increase in revenues of $105.3 million. The increase was also due to higher revenues related to on-site inspection, maintenance and refurbishment work of $23.1 million and components manufacturing of $19.2 million.

Operating income increased $17.6 million to $24.0 million in the three months ended March 31, 2026 compared to $6.5 million for the corresponding period of 2025. The increase was primarily related to the operating income impact of the changes in revenues noted above as well as a favorable shift in our product mix. These increases were partially offset by a $1.7 million increase in expenses associated with acquisition and restructuring-related activities.

Unallocated Corporate

Three months ended March 31, 2026 vs. 2025

Unallocated corporate expenses increased $8.9 million to $16.5 million in the three months ended March 31, 2026 compared to $7.6 million the corresponding period of 2025. The increase was primarily related to higher expenditures for legal and consulting costs associated with merger and acquisition related activities of $3.0 million and restructuring related activities $1.0 million when compared to the corresponding period of the prior year.

Provision for Income Taxes

Provision for Income Taxes						$	16,127					$	16,291					$	(164)
Effective Tax Rate						15.0%						17.7%

We primarily operate in the U.S., Canada and various other foreign jurisdictions and we recognize our U.S. income tax provision based on the U.S. federal statutory rate of 21%, our Canadian tax provision is based on the Canadian local statutory rate of approximately 25%, and other foreign jurisdictions at various enacted rates.

Our effective tax rate for the three months ended March 31, 2026 was 15.0% as compared to 17.7% for the three months ended March 31, 2025. The effective tax rates for the three months ended March 31, 2026 and March 31, 2025 were lower than the U.S. corporate federal income tax rate of 21% primarily due to excess tax benefits associated with equity compensation.

Backlog

Backlog represents the dollar amount of revenue we expect to recognize in the future from contracts awarded and in progress. Not all of our expected revenue from a contract award is recorded in backlog for a variety of reasons, including that some projects are awarded and completed within the same reporting period.

Our backlog is equal to our remaining performance obligations under contracts that meet the criteria in Financial Accounting Standards Board Topic Revenue from Contracts with Customers, as discussed in Note 3 to our condensed consolidated financial statements included in this Report. It is possible that our methodology for determining backlog may not be comparable to methods used by other companies.

24

Table of Contents

We are subject to the budgetary and appropriations cycle of the U.S. Government as it relates to our Government Operations segment. Backlog may not be indicative of future operating results and projects in our backlog may be cancelled, modified or otherwise altered by customers.

						March 31, 2026						December 31, 2025
						(In approximate millions)
Government Operations						$	6,931					$	5,541
Commercial Operations						1,720						1,720
Total Backlog						$	8,651					$	7,261

We do not include the value of our unconsolidated joint venture contracts in backlog.

As of March 31, 2026, our ending backlog was $8,650.8 million, which included $2,367.4 million of unfunded backlog related to U.S. Government contracts. We expect to recognize approximately 60% of the revenue associated with our backlog by the end of 2027, with the remainder to be recognized thereafter.

Major new awards from the U.S. Government are typically received following Congressional approval of the budget for the U.S. Government's next fiscal year, which starts October 1, and may not be awarded to us before the end of the calendar year. Due to the fact that most contracts awarded by the U.S. Government are subject to these annual funding approvals, the total values of the underlying programs are significantly larger.

The value of unexercised options excluded from backlog as of March 31, 2026, including previous awards, was approximately $1,400 million. We expect $900 million to be awarded in 2030 and $500 million to be awarded in 2035, subject to annual Congressional appropriations.

Liquidity and Capital Resources

New Credit Facility

On November 10, 2025, we entered into a second Amended and Restated Credit Agreement (the "New Credit Facility") with Wells Fargo Bank, National Association, as administrative agent, and the other lenders party thereto, which amended and restated our then-existing secured credit facility (the "Former Credit Facility"), which consisted of a $750 million senior secured revolving credit facility (the "Revolving Credit Facility") and a $250 million senior secured term A loan (the "Term Loan"). The Revolving Credit Facility and the Term Loan were repaid, in their entirety, with the proceeds from the 2030 Notes as discussed below. The New Credit Facility includes a $1.25 billion senior secured revolving credit facility. The proceeds of loans under the New Credit Facility are available for working capital needs, permitted acquisitions and other general corporate purposes.

The New Credit Facility is scheduled to mature on November 10, 2030, subject to an early maturity trigger if on any date the aggregate outstanding principal amount of unsecured indebtedness due within 91 days thereof is in excess of 100% of EBITDA, as defined in the New Credit Facility, for the last four full fiscal quarters. However, this early maturity trigger will not apply if (1) the total Net Leverage Ratio is less than or equal to 2.00 to 1.00 or (2) liquidity is at least 125% of such outstanding unsecured indebtedness. The Company’s obligations under the New Credit Facility are guaranteed by the same guarantors that guarantee the 2030 Notes. The New Credit Facility is secured by first-priority liens on certain assets owned by the Company and the guarantors (other than its subsidiaries comprising a portion of its Government Operations segment), provided such liens may be released if the Company obtains investment grade ratings of at least BBB- from S&P or Baa3 from Moody's and no default or event of default exists.

The New Credit Facility allows for additional parties to become lenders and, subject to certain conditions, for the increase of the commitments under the New Credit Facility, subject to an aggregate maximum for all additional commitments of (1) the greater of (a) $600 million and (b) 100% of EBITDA, as defined in the New Credit Facility, for the last four full fiscal quarters, plus (2) additional amounts provided the Company is in compliance with a pro forma first lien leverage ratio test 3.00 to 1.00 or less.

Outstanding loans under the New Credit Facility bear interest at our option at either (i) the Term SOFR rate plus a margin ranging from 1.00% to 1.75% per year or (ii) the base rate (the highest of (x) the administrative agent's prime rate, (y) the Federal Funds rate plus 0.50% and (z) the Term SOFR rate for a one-month tenor plus 1.00%) plus a margin ranging from 0% to 0.75% per year. In addition, the Company will be charged (1) a commitment fee of between 0.15% and 0.225% per year on

25

Table of Contents

the unused portion of the New Credit Facility, (2) a letter of credit fee of between 1.00% and 1.75% per year with respect to the amount of each financial letter of credit issued under the New Credit Facility, and (3) a letter of credit fee of between 0.75% and 1.05% per year with respect to the amount of each performance letter of credit or commercial letter of credit issued under the New Credit Facility. The applicable margin for loans, the commitment fee and the letter of credit fees set forth above will vary quarterly based on the Company's consolidated total net leverage ratio.

The Company may prepay all loans under the New Credit Facility at any time without premium or penalty (other than customary Term SOFR rate breakage costs), subject to notice requirements.

The New Credit Facility contains representations and warranties, affirmative and negative covenants and events of default that the Company considers customary for an agreement of this type, including covenants setting a maximum consolidated total net leverage ratio and a minimum consolidated interest coverage ratio. If any event of default relating to bankruptcy or other insolvency events occurs with respect to the Company, the lenders’ commitments under the New Credit Facility will automatically terminate and all outstanding obligations under the New Credit Facility will immediately become due and payable. If any other event of default occurs, the lenders will be permitted to terminate their commitments under the New Credit Facility, accelerate all outstanding obligations under the New Credit Facility and exercise other rights and remedies, including the commencement of foreclosure or other actions against the collateral. Based on the total net leverage ratio applicable at March 31, 2026, the margin for Term SOFR and base rate loans was 1.50% and 0.50%, respectively, the letter of credit fee for financial letters of credit and performance letters of credit was 1.50% and 0.90%, respectively, and the commitment fee for the unused portion of the New Credit Facility was 0.20%.

The New Credit Facility includes financial covenants that are evaluated on a quarterly basis, based on the rolling four-quarter period that ends on the last day of each fiscal quarter. The maximum permitted leverage ratio is 4.00 to 1.00, which may be increased to 4.50 to 1.00 for up to four consecutive fiscal quarters after a material acquisition. The minimum consolidated interest coverage ratio is 3.00 to 1.00. In addition, the New Credit Facility contains various restrictive covenants, including with respect to debt, liens, investments, mergers, acquisitions, dividends, equity repurchases and asset sales. As of March 31, 2026, we were in compliance with all covenants set forth in the New Credit Facility.

As of March 31, 2026, letters of credit issued under the New Credit Facility totaled $1.4 million. We had no outstanding borrowings and $1,248.6 million available under the New Credit Facility for borrowings and to meet letter of credit requirements.

The New Credit Facility generally includes customary events of default for a secured credit facility. Under the New Credit Facility, (1) if an event of default relating to bankruptcy or other insolvency events occur with respect to the Company, all related obligations will immediately become due and payable; (2) if any other event of default exists, the lenders will be permitted to accelerate the maturity of the related obligations outstanding; and (3) if any event of default exists, the lenders will be permitted to terminate their commitments thereunder and exercise other rights and remedies, including the commencement of foreclosure or other actions against the collateral.

If any default occurs under the New Credit Facility, or if we are unable to make any of the representations and warranties in the New Credit Facility, we will be unable to borrow funds or have letters of credit issued under the New Credit Facility.

Senior Notes due 2028

We issued $400 million aggregate principal amount of 4.125% senior notes due 2028 (the "Senior Notes due 2028") pursuant to an indenture dated June 12, 2020 (the "2020 Indenture"), among the Company, certain of our subsidiaries, as guarantors, and U.S. Bank Trust Company, National Association (formerly known as U.S. Bank National Association) ("U.S. Bank"), as trustee. The Senior Notes due 2028 are guaranteed by each of the Company's present and future direct and indirect wholly owned domestic subsidiaries that is a guarantor under the Credit Facility.

Interest on the Senior Notes due 2028 is payable semi-annually in cash in arrears on June 30 and December 30 of each year at a rate of 4.125% per annum. The Senior Notes due 2028 will mature on June 30, 2028.

We may redeem the Senior Notes due 2028, in whole or in part, at any time at a redemption price equal to 100.0% of the principal amount to be redeemed plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

The 2020 Indenture contains customary events of default, including, among other things, payment default, failure to comply with covenants or agreements contained in the 2020 Indenture or the Senior Notes due 2028 and certain provisions

26

Table of Contents

related to bankruptcy events. The 2020 Indenture also contains customary negative covenants. As of March 31, 2026, we were in compliance with all covenants set forth in the 2020 Indenture and the Senior Notes due 2028.

Senior Notes due 2029

We issued $400 million aggregate principal amount of 4.125% senior notes due 2029 (the "Senior Notes due 2029") pursuant to an indenture dated April 13, 2021 (the "2021 Indenture"), among the Company, certain of our subsidiaries, as guarantors, and U.S. Bank, as trustee. The Senior Notes due 2029 are guaranteed by each of the Company's present and future direct and indirect wholly owned domestic subsidiaries that is a guarantor under the Credit Facility.

Interest on the Senior Notes due 2029 is payable semi-annually in cash in arrears on April 15 and October 15 of each year, at a rate of 4.125% per annum. The Senior Notes due 2029 will mature on April 15, 2029.

We may redeem the Senior Notes due 2029, in whole or in part, at any time at a redemption price equal to 100.0% of the principal amount to be redeemed if the redemption occurs on or after April 15, 2026, in each case plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

The 2021 Indenture contains customary events of default, including, among other things, payment default, failure to comply with covenants or agreements contained in the 2021 Indenture or the Senior Notes due 2029 and certain provisions related to bankruptcy events. The 2021 Indenture also contains customary negative covenants. As of March 31, 2026, we were in compliance with all covenants set forth in the 2021 Indenture and the Senior Notes due 2029.

2030 Notes and Capped Call Transactions

2030 Notes

In November 2025, the Company issued $1.25 billion aggregate principal amount of 0% Convertible Senior Notes due 2030 (the "2030 Notes"), including the exercise in full of the initial purchasers' option to purchase up to an additional $150.0 million principal amount of the 2030 Notes. The 2030 Notes were issued pursuant to an Indenture, dated November 19, 2025 (the "Indenture"), among the Company, certain of our subsidiaries, as guarantors, and U.S. Bank Trust Company, National Association, as trustee. The 2030 Notes are guaranteed by each of the Company's present and future direct and indirect wholly owned domestic subsidiaries that guarantee its existing and future capital markets indebtedness.

The conversion rate for the 2030 Notes will initially be 3.8094 shares of common stock per $1,000 principal amount of the 2030 Notes, which is equivalent to an initial conversion price of approximately $262.51 per share of common stock. The conversion rate is subject to adjustment upon certain events. Upon conversion, the Company will settle conversions by paying cash up to the aggregate principal amount of the 2030 Notes to be converted and paying or delivering, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock, at its election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the 2030 Notes being converted, based on the applicable conversion rate(s).

The 2030 Notes will mature on November 1, 2030, unless earlier converted, redeemed or repurchased. The 2030 Notes will not bear regular interest, and the principal amount of the 2030 Notes will not accrete. However, special interest and additional interest, if any, may accrue on the 2030 Notes at a combined rate per annum not exceeding 0.50% upon the occurrence of certain events as described in the Indenture.

The Company may not redeem the 2030 Notes at its option before November 6, 2028. The Company will have the option to redeem the 2030 Notes, in whole or in part (subject to the partial redemption limitation described below), at any time, and from time to time, on or after November 6, 2028 and before the 26th Scheduled Trading Day (as defined in the Indenture) immediately before the maturity date, at a cash redemption price equal to the principal amount of the 2030 Notes to be redeemed, plus accrued and unpaid special interest and additional interest, if any, to, but excluding, the redemption date, but only if certain conditions are met.

On or after August 1, 2030, until the close of business on the second Scheduled Trading Day (as defined in the Indenture) immediately before the maturity date, the 2030 Notes will be convertible at the option of the noteholders at any time.

Before August 1, 2030, noteholders will have the right to convert their 2030 Notes only under the following circumstances: (1) during any fiscal quarter commencing after the fiscal quarter ending on March 31, 2026, if the last reported sale price of the Company’s common stock exceeds 130% of the conversion price for each of at least 20 trading days (whether

27

Table of Contents

or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter; (2) during the five consecutive business days immediately after any ten consecutive trading day period if the trading price per $1,000 principal amount of 2030 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of common stock on such trading day and the conversion rate on each Trading Day; (3) upon the occurrence of specified corporate events or distributions on the common stock as set forth in the Indenture; or (4) if the Company calls the 2030 Notes for redemption.

If the Company undergoes a Fundamental Change (as defined in the Indenture), then, subject to certain exceptions, noteholders may require the Company to repurchase their 2030 Notes in whole or in part for cash at a price equal to the principal amount of the 2030 Notes to be repurchased, plus accrued and unpaid special interest and additional interest, if any, to, but excluding, the Fundamental Change Repurchase Date (as defined in the Indenture). The definition of Fundamental Change includes, among other things, certain business combination transactions involving the Company and certain de-listing events with respect to the common stock.

Capped Call Transactions

In connection with the pricing of the 2030 Notes and the exercise by the initial purchasers of their option in full to purchase additional 2030 Notes, respectively, the Company paid $131.9 million to enter into privately negotiated capped call transactions (the “Capped Call Transactions”) with affiliates of certain of the initial purchasers and certain other financial institutions (the “Option Counterparties”). The Capped Call Transactions have an expiration date of November 1, 2030 but may be redeemed earlier, subject to certain conditions.

The Capped Call Transactions cover, subject to anti-dilution adjustments substantially similar to those applicable to the 2030 Notes, the number of shares of common stock initially underlying the 2030 Notes. The Capped Call Transactions are expected generally to reduce the potential dilution to the holders of common stock upon any conversion of the 2030 Notes and/or offset any potential cash payments the Company is required to make in excess of the principal amount of converted 2030 Notes, as the case may be, with such reduction and/or offset subject to a cap. The cap price of the Capped Call Transactions will initially be $396.24 per share of common stock, which represents a premium of 100% over the last reported sale price of the common stock of $198.12 per share on November 5, 2025, and is subject to certain adjustments under the terms of the Capped Call Transactions.

The Capped Call Transactions are separate transactions (in each case entered into by the Company with the Option Counterparties), are not part of the terms of the 2030 Notes and will not change the holders’ rights under the 2030 Notes. Holders will not have any rights with respect to the Capped Call Transactions. The Capped Call Transactions qualify for a scope exception from derivative accounting for instruments that are both indexed to the issuer's own stock and classified in stockholders' equity on our consolidated balance sheets.

The 2030 Notes and the Capped Call Transactions have been integrated for tax purposes. The impact of this tax treatment results in the Capped Call Transactions being deductible with the cost of the Capped Call Transactions qualifying as original issue discount for tax purposes over the term of the 2030 Notes.

Other Arrangements

We have posted surety bonds to support regulatory and contractual obligations for certain decommissioning responsibilities, projects and legal matters. We utilize surety bond facilities to support such obligations, but the issuance of surety bonds under those facilities is typically at the surety's discretion, and the surety bond facilities generally permit the surety, in its sole discretion, to terminate the facility or demand collateral. Although there can be no assurance that we will maintain our surety bond capacity, we believe our current capacity is adequate to support our existing requirements for the next 12 months. In addition, these surety bonds generally indemnify the beneficiaries should we fail to perform our obligations under the applicable agreements. We, and certain of our subsidiaries, have jointly executed general agreements of indemnity in favor of surety underwriters relating to surety bonds those underwriters issue. As of March 31, 2026, surety bonds issued and outstanding under these arrangements totaled approximately $359.6 million.

Similarly, we have provided letters of credit and bank guarantees to governmental agencies and contractual counterparties to support regulatory and contractual obligations for certain decommissioning responsibilities, projects and legal matters. We utilize our New Credit Facility and a bilateral letter of credit facility to support such obligations, but the issuance of letters of credit and bank guarantees under our bilateral letter of credit facility is at the issuer's discretion, and our bilateral letter of credit facility generally permits the issuer, in its sole discretion, to demand collateral if the issuer does not otherwise have the benefit of the collateral under our New Credit Facility. Although there can be no assurance that we will maintain our bilateral letter of credit facility capacity, we believe our current capacity, together with capacity under our New Credit Facility, is adequate to

support our existing requirements for the next 12 months. As of March 31, 2026, letters of credit and bank guarantees issued and outstanding under our bilateral letter of credit facility totaled approximately $50.7 million, and such letters of credit and bank guarantees are secured by the collateral under our New Credit Facility.

Long-term Benefit Obligations

As of March 31, 2026, we had underfunded defined benefit pension and postretirement benefit plans with obligations totaling approximately $158.1 million. These long-term liabilities are expected to require use of our resources to satisfy future funding obligations. Based largely on statutory funding requirements, we expect to make contributions of approximately $16.3 million for the remainder of 2026 related to our pension and postretirement plans. We may also make additional contributions based on a variety of factors including, but not limited to, tax planning, evaluation of funded status and risk mitigation strategies.

Other

Cash, Cash Equivalents, Restricted Cash and Investments

Our domestic and foreign cash and cash equivalents, restricted cash and cash equivalents and investments as of March 31, 2026 and December 31, 2025 were as follows:

						March 31, 2026						December 31, 2025
						(In thousands)
Domestic						$	453,799					$	501,259
Foreign						74,475						14,188
Total						$	528,274					$	515,447

Our working capital increased by $53.8 million to $942.2 million at March 31, 2026 from $888.3 million at December 31, 2025, primarily due to changes in contracts in progress and advance billings on contracts due to the timing of project cash flows and decreases in accrued employee benefits offset partially by increases in accounts payable and accrued liabilities.

Our net cash provided by operating activities increased by $42.0 million to $92.6 million in the three months ended March 31, 2026, compared to cash provided by operating activities of $50.7 million in the three months ended March 31, 2025. The increase in cash provided by operating activities was primarily attributable to the timing of vendor payments and project cash flows.

Our net cash used in investing activities decreased by $109.4 million to $46.9 million in the three months ended March 31, 2026, compared to cash used in investing activities of $156.4 million in the three months ended March 31, 2025. The decrease in cash used in investing activities was primarily attributable to the acquisition of A.O.T. on January 3, 2025.

Our net cash used in financing activities increased by $119.0 million to $34.2 million in the three months ended March 31, 2026, compared to cash provided by financing activities of $84.8 million in the three months ended March 31, 2025. The increase in cash used in financing activities was primarily due to net borrowings of long-term debt of $141.9 million in the corresponding period in the prior year.

At March 31, 2026, we had restricted cash and cash equivalents totaling $8.0 million, $4.8 million of which was held for future decommissioning of facilities (which is included in Other Assets on our condensed consolidated balance sheets) and $3.2 million of which was held to meet reinsurance reserve requirements of our captive insurer.

At March 31, 2026, we had long-term investments with a fair value of $7.9 million and our investment portfolio consisted entirely of mutual funds. These equity securities are carried at fair value with the unrealized gains and losses reported in earnings.

Cash Requirements

As discussed in Note 2 to our condensed consolidated financial statements, we announced our intention to acquire PCG. We expect to make a significant cash investment during 2026 to complete this acquisition.

We believe we have sufficient cash and cash equivalents and borrowing capacity, along with cash generated from operations and continued access to capital markets, to satisfy our cash requirements for the next 12 months and beyond.

Item 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our exposures to market risks have not changed materially from those disclosed in Item 7A of our 2025 10-K.

Item 4.    CONTROLS AND PROCEDURES

As of the end of the period covered by this Report, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) adopted by the Securities and Exchange Commission ("SEC") under the Exchange Act). This evaluation was conducted under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer. Our disclosure controls and procedures were developed through a process in which our management applied its judgment in assessing the costs and benefits of such controls and procedures, which, by their nature, can provide only reasonable assurance regarding the control objectives. You should note that the design of any system of disclosure controls and procedures is based in part upon various assumptions about the likelihood of future events, and we cannot assure you that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. Based on the evaluation referred to above, our Chief Executive Officer and Chief Financial Officer concluded that the design and operation of our disclosure controls and procedures are effective as of March 31, 2026 to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and such information is accumulated and communicated to management as appropriate to allow timely decisions regarding disclosure.

On May 20, 2025, we completed the acquisition of Kinectrics and started the process of integrating Kinectrics into our operations and internal control structure. Certain internal controls over financial reporting related to Kinectrics have been impacted by changes made to conform to existing controls and procedures of BWXT. Other than the changes resulting from the Kinectrics acquisition, there have been no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. The integration of Kinectrics is expected to be completed in 2026.
